What are the three types of water movement?

Answer:

  1. Laminar flow is the most common in the aquarium and simply means that the water is moving steadily and in only one direction. It is most often produced by powerheads. In the ocean, this type is found at deeper areas of the reef.

  2. Surge is similar to laminar flow, only stronger, for a shorter duration, and followed by a weaker reverse flow.
    You think of waves when talking about water movement in the ocean right? Waves are created by winds and this best illustrates surge. This back and forth type of aquarium water movement is very beneficial to corals in your tank.

  3. Turbulence is the random swirling and flow of water in all directions. This happens when currents collide with each other. Of the three types, turbulence is the most desirable and the most difficult to replicate.
